Qwiic Pressure Sensor - LPS25HB

The LPS25HB is an absolute pressure sensor which means that it has an internal vacuum as a reference. You can use this absolute pressure sensor to inform a drone autopilot of altitude, make a personal weather station, or maybe even help test someone’s lung function. As part of the Qwiic system adding more capabilities like data logging with the Qwiic OpenLog.

The LPS25HB is the newest version of the LPS25H by STMicroelectronics featuring the widest range of sensing pressures (26 kPa to 126 kPa) and very high precision (as low as 1 Pa RMS, which equates to approximately 8 centimeters of air at sea level). Other features such as the 25 Hz update rate and durability to withstand nearly 2.5 MPa over-pressure make this a great choice for absolute pressure sensor. In addition to the Qwiic connectors this sensor breakout exposes the I2C and SPI lines as plated through hole (PTH) connections on either side. SPI access will allow for even faster communication with the sensor (up to 10 MHz).
